Hello,
This is the same problem that Adrian Thearle described on the
freebsd-questions list several months ago.
http://lists.freebsd.org/pipermail/freebsd-questions/2008-August/181476.html
I have a ral(4), Ralink RT2860 specifically, acting as the Host AP for
a wireless subnet. I have three active clients on this subnet: two
TiVos and the laptop I am composing this email on presently. All
three can associate with the ral device, get an IP address via DHCP,
communicate with the greater internet over a NAT, etc.
The problem is that the three hosts are unable to communicate with
each other. The most obvious symptom of this problem (for me) is that
the TiVos cannot discover each other. They send out subnet broadcast
packets on UDP port 2190. These packets are received by the AP.
They are not, however, received by any other hosts on the subnet. I
have confirmed this using Wireshark on this laptop.
I did a lot of googling for subnet broadcast issues, but upon
discovering Adrian's message, I realized I ought to check the very
basic connectivity I was assuming: can the hosts ping each other?
They cannot. They can all ping the AP (or be pinged by it, since I
don't have console access to the TiVos).
Wireshark confirms Adrian's finding: the ARP request is never
acknowledged. My laptop cannot ascertain the MAC address of either
TiVo and therefore cannot send the unicast ICMP echo request.
My network was working fine until I switched out an old Netgear
802.11b WAP connected through an fxp interface with this new ral
device. (I also switched to WPA2 during this change.) I am quite
certain my network configuration is sane, and my wireless hosts could
ping each other previously, the TiVos could see each other, etc.
While it seems counterintuitive, the ral device seems to be the common
thread in this problem. Somehow its clients cannot receive each
other's broadcasts (ARPs and subnet broadcasts that both transmit as
all-ones at layer 2). Anyone have any ideas on how this could be? My
best guess is that the ral device or driver is flawed, but I've
reached a dead end in any case. Hopefully a driver update can fix this.
The device is configured as follows (from hostname.ral0):
wpa wpapsk $(wpa-psk <nwid> <shared secret>) wpaakms psk
nwid <nwid>
OpenBSD 4.4 on i386. dmesg attached.
Any and all help appreciated!
Thanks,
Curtis Dunham
